Springtime Emergency Air Conditioning Repair for a residential customer near Family Farm. Came out on water leak service call Water dripping from staircase to attic from a secondary drain pan that was full and was dripping over the corner Both units in attic are tied together. Installed shutoff to one side of drain line and coupling on other drain line after cleared and double checked drain line was clear put lines back together. Found cracked upstairs secondary pan meaning if it gets water in that pan will have another water leak. Cleared secondary drain line from pan to allow water to leave secondary pan properly.
